A new finding in selective Baeyer-Villiger oxidation of α-fluorinated ketones; a new and practical route for the synthesis of α-fluorinated esters

α-Fluorinated esters were effectively prepared by the Baeyer-Villiger oxidation of α-fluorinated ketones with m-chloroperbenzoic acid (m-CPBA) under mild conditions. The yield of the esters was influenced by the choice of solvent, base, and substituent on the aryl group of the ketones. 4-Methoxyphenyl substituted fluoroketones were oxidized almost quantitatively with m-CPBA within 10 min to 12 h at room temperature using 1,1,1,3,3,3-hexafluoro-2-propanol (HFIP) as a cosolvent with CH2Cl2 (1:1, v/v) and aqueous buffer (KH2PO4-NaOH, pH 7.6) as an additive base. The oxidation reaction rates of α-fluorinated ketones were higher than those of the corresponding non-fluorinated ketones. The fluorine atom at α-position of fluoromethyl aryl ketones enhanced the reactivity in the Baeyer-Villiger oxidation.

Process for preparing compounds containing a difluoromethylene group in a position α to an oxygen atom

A process for the preparation of compounds containing a difluoromethylene group in a position α to an oxygen atom. An alcohol or a phenol is brought into contact with trifluoroacetic acid or a halide or anhydride thereof in anhydrous liquid hydrofluoric acid, in the presence of boron trifluoride, in a quantity such that the absolute pressure of boron trifluoride is at least about one bar. The compounds obtained according to the invention are used as synthesis intermediates in the pharmaceutical, plant-protection, and dye industries, as anesthetics and as additives for lubricating oils.
